Depending on the mode selected, displays the following: network activity information, whether
the port is configured for Full Duplex operation, maximum speed operation, or whether network
errors are occurring on the port. See "LED Mode Select Button and Indicator LEDs" below for
more information.
The flashing behavior is an on/off cycle once every 1.6 seconds, approximately.

Meaning
A module is installed in the switch module slot corresponding to the letter and the module
is undergoing or has passed self test. This also occurs when you install a module when
the switch is already powered on ("hot swap").
A module is not installed in the switch module slot corresponding to the letter.
The module status LED flashes very briefly when a module is being hot swapped. If the LED
flashes for a prolonged time, the module in the slot corresponding to the letter has failed
self test or encountered some other fault condition. See chapter 4, "Troubleshooting" for
a more information.
Indicates that the port Mode LEDs are displaying network activity information.
Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode.
Indicates that the port Mode LEDs are lit for ports that are operating at their maximum
possible link speed -- for any Gigabit-capable connection, that would be 1000 Mbps; for
the 10/100-TX ports and 100-FX ports, that would be 100 Mbps.
Indicates that specific error packets are being detected on the port. In this mode, the Mode
LED for the port will flash briefly for each error packet that is detected, for example CRC
errors or late collisions. See chapter 4, "Troubleshooting" for more information.
Switch Module LEDs
Meaning
Indicates the port is enabled and receiving a link beat signal (for the twisted-pair
ports), or a strong enough light level (for the fiber-optic ports) from the connected
device.
One of these conditions exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
• the port has been disabled through the switch console, the web browser
interface, ProCurve Manager, or other network management tool.
The port has failed self test. The switch Fault, Self Test LEDs, and appropriate
module status LEDs will flash simultaneously.
